486, ISA bus & Unix/386

[david nugent]

Is anyone currently running SCO or Interactive Unix (or any other 386 Unix
for that matter) on a 486 box?

In particular, I need any information about experiences with:

  a) ISA bus technology, running a 386 Unix (which ones currently
     support ISA?)
     
  b) Ethernet cards available for the ISA bus, and which tcp-ip
     software is available for them (and does it work? :-))
     
  c) Any problems running a 386 Unix on a 25 or 33 MHZ 486 box

The proposed system will be:


  486 box, 16-20 meg of RAM
  tcp-ip; using GARP (Gateway's Novell tcp-ip bridge) with all the
    usual hardware requirements, supporting up to 40 connections
  tape drive (any around which work with ISA?)
  intelligent serial card, 16-32 ports (ditto)


We've set up equivalent systems using 386 boxes with an AT-compatible bus,
and had a few problems with the faster machines, and found a few problems
which could be worked around, but the requirement here is _definitely_ for
a 486, or possible a 386 with a dual processor card.
  
Any information appreciated.  Please respond by mail - I'll post a summary
if there is any interest.
